A 5.1-magnitude quake struck near the city of La Habra, about 20 miles (32 kilometers) southeast of downtown Los Angeles. The tremor was felt across California on Friday, along with at least 100 aftershocks.

The earthquake took place at 9:09 PM (04:09 GMT am on Saturday)
nearly 1,6 km of the city of La Habra, or 6,4 km north of the
city of Fullerton, Orange county, said the United States
Geological Survey (USGS). According to the local media, the
shakes lasted from 10 to 15 seconds.

The tremor was felt across at least five counties of California,
such as Orange, Los Angeles, Ventura, Riverside, and San
Bernardino counties.

Residents in cities like Encinitas, Del Mar, Oceanside, San Diego
and San Marcos reported feeling the shakes, San Diego news
reported.

There have been at least 100 aftershocks following the major
quake, said USGS. At least five aftershocks have been recorded
ranging from magnitudes 2.7 to 3.6. The strongest one happened at
9:33 p.m. on Friday (04:33 GMT am on Saturday) also in La Habra.

USGS also added that the strikes may also continue for several
days to weeks, but will “decay in frequency and
magnitude,” the USGS warned.

No injuries were reported, however the tremor displaced at least
50 residents in Fullerton, about 5 miles (8 km) from the
epicenter, because of minor damage, Fullerton Police Lieutenant
Mike Chlebowski said.

"Five houses and 20 apartments were damaged by the
earthquake, but the fire department is in the process of
determining the extent," he said, adding that a water main
break in the city forced the closure of surrounding streets due
to flooding.

Brea police reported of water main and gas main leaks and a
rockslide caused by the quake, in La Habra, Fullerton and La
Mirada, said LA Times. Fullerton police closed the area in the
corner of Rosecrans and Gilbert avenues.

"Tonight's earthquake is the second in two weeks, and reminds
us to be prepared," L.A. Mayor Eric Garcetti said in an
official statement.

Garcetti added that the LA police and Fire Departments had found
no damage within the city limits.

The LA Fire Department said on Saturday it had called off its
"earthquake mode."

About 3,000 customers of the Southern California Edison Company
have also been left without power.

Disneyland in Orange County temporarily halted rides in response
to the quake and asked visitors to remain seated.

A brick wall collapse, water sloshing around a swimming pool and
wires and trees swaying back and forth have been reported by
LA-based KNX-AM news.

"A lot of the glass in the place shook like crazy," a
witness told KNX-AM news. "It started like a roll and then it
started shaking like crazy. Everybody ran outside, hugging each
other in the streets."

The quake raised concerns among some seismologists.

“It isn't big, but it is significant. There is a five percent
chance that it will be followed by something larger in the next
24-48 hours,” Tom Rockwell, a seismologist San Diego State
University, told San Diego news.

Geologists at the California Institute of Technology in Pasadena
said the temblor was shallow, at a depth of 1.6 km. According to
Robert Graves of CalTech, "earthquakes in California tend to
be deeper than that so it's a little bit anomalous."

Meanwhile, preliminary data suggest that the recent strike might
have been caused by the earthquake that shook Californian coast
decades ago.

“It’s related to the Puente Hills thrust fault, which caused
the Whittier Narrows earthquake back in 1987,” said Caltech
seismologist Egill Hauksson.

On March, 10, California was struck by a magnitude 6.9 earthquake
which affected its northern part. With an epicenter 50 miles west
of the city of Eureka, it was widely felt across the region by
thousands of people, and followed by more than a half-dozen
aftershocks.
